摘要:
2016 年9 月，采用Hoagland 营养液静止水培和泥炭藓作为基质了对报春石斛Dendrobium primulinum Lindl.试管苗进行了3 个月的培养，比较不同基质对报春石斛根系生长的影响。检测结果表明，水培苗根系生长速度慢，但是地上部分茎杆粗壮，能快速生长，适生性较强。光镜观察水培苗和基质苗根尖、成熟区和根毛区，结果显示，水培苗根尖皮层细胞比较规则紧凑，细胞间隔比较小，而基质培养苗根尖细胞排列较松散，排列不规则；基质培养苗根系的中柱部分髓质较水培苗的大，且存在体积较大的淀粉粒。对两种栽培方式的新生根进行Evan blue 染色，发现水培根成熟区较基质培养的更具活力。试验表明，报春石斛根系能够很好的适应水生环境。
Abstract:
Experiments were conducted in September 2016 on culture of Dendrobium primulinum in hydroponics (Hoagland) and substrate(sphagnum) for comparing their root system growth. Determinations were implemented three months later. The result showed that root system growthof water cultured D. primulinum was slower but stem growth was larger than that of substrate cultured. Light microscope of root tip, mature zone androot hair zone of the two cultured seedlings demonstrated that cortical cells of root tip from water cultured seedlings were more compact and cellinterval more smaller. The area of the pith was less in the stele of substrate cultivated and there were large starch grains. New root from the two testedseedlings was Evan blued, the result indicated that root activity of water cultured had better effect. The experiment concluded that D. primulinumcould grow well in hydroponics.
